Looking to add a little color to your formal wear?
You included the snippet swatch.liquid with the name of a product option — 'Color' — that does not belong to your product.
'Color'
Use {% include 'swatch' with 'name of your product option here' %}
{% include 'swatch' with 'name of your product option here' %}
Example: {% include 'swatch' with 'Color' %}
{% include 'swatch' with 'Color' %}
This is case-sensitive! Do not put in 'color' if your product option name is 'Color'.
